    Re: Samsung 50" Plasma No Video

    On this set a bad Y-main and kill the X-main and vice versa due to the design combining the energy recovery across both boards.

      Alright, I'm not sure exactly what you want me to check but I've been doing some comparison readings and hopefully this will make sense.

      I tested these pins against a ground and all the readings came back positive on the new board and pins 1 2 & 3 were 0.0 on the old board so I believe that is all in order.

          I think my X main is good so my next step is going to be to pull the new Y-main and compare it to the old board.

            Ah Ha. I may have a culprit. So in testing the connection between the X main and Y main I've found the following.

            On the Y Main; All 3 ground pins come back as 0L so i'm pretty sure that is not good. And of the 5 pins marked ERC two come back as 0.0 where the others give a positive reading.

              Samsung UE65RU7090UXZT main board issue no video out. BN94-14180M
              by alltvrepairs
              Hi,

              I have confirmed that I have a mainboard problem.
              I have tracked no hardware issued on board so might be a software dump required.

              I have searched a bit but wasn't able to find anything for my screen:

              Here are some more details:
              Panel: cy-nn065hgev1h
              Main: BN94-14180M P08F

              Your help much appreciated!

              Samsung UN55MU6103F video problem; has colored stripes on the display
              by alro7779
              Hello, everyone!

              A co-worker gave me a 55-inch Samsung TV model UN55MU6103F so I can try to fix the following problem... As soon as I plug it in to the wall, the TV turns on, and the display shows a few stripes all over the screen. I took off the back cover and disconnected both ribbon cables that go to the display (one at a time) so by doing that I can narrow down the bad section of the problem, but in both cases the display turns black. I know there are some voltages that I have to check (VGH, VGL, etc.) but don't know what reading each has to show. If anyone could guide me on this,...

              Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
              by Asraf Atb
              Hi everyone,

              Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

              Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

              I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

              Samsung PN50C540G3FXZA 50" Plasma, power cycling, Y-Main problem, Canada
              by bcstedt
              Just starting to crack into this one and wanted to get the ball rolling.

              At power on (plug in), power light on, relays click, repeat (sometimes)

              After disconnecting Y-Main from SMPS power stays on and boot up jingle is heard from speakers

              Removed Y-Main for inspection and testing
